The Dun-bar – 2011 (NL)
The Dun-bar (Cosmia trapezina) has a diagonal transverse line on the forewing that runs from the costa to the dorsum. The post-median line runs from the costa at an acute angle to the dorsum. In the resting position, it, therefore, seems as if a ‘V’ is drawn on the wings. The kidney mark is clearly visible through the black dot that is present in it. There are also specimens that are light-colored and where the band between the two cross lines is very dark-colored. It flies in one generation from June to October and the wingspan is 25-33mm. Host plant: Oak, Birch, Elm, Blackthorn, Hawthorn, Hazel, Willow, and Poplar. Dutch name: Hyena. Frisian name: Hyenaûltsje.
